Numerical simulation of temperature field distribution of graphene composites
摘要
Abstract
Highly-thermal-conductive graphene composite material has excellent thermophysical properties, as well as the advantages of low density and good thermal conductivity in comparison with copper and other traditional thermal management materials, so it is an ideal material for electronic packaging. But its disadvantages of high cost and low strength have severely restricted its application. Based on the highly-thermal-conductive graphene composite material prepared by the research group, this paper adopted the composite material as key heat dissipation components, which not only utilized the high directional thermal conductivity of composite material, but also resolved the issue of high cost and low mechanical strength, successfully realized a temperature reduction of 11.5 ℃ on the surface of heat source through temperature field simulation with the ANSYS software. This prove that adopting the new highly-thermal-conductive graphene composite material to replace the traditional materials in special areas can improve the thermal conductivity of the entire structure. The research results can provide technical support for applying new thermal management materials in relevant areas.关键词
